Post by sean-barton on Ambiguous namespace in library dependencies ^{CODESYS Forge talk (Post)}
I've created a very basic version of this problem as a project. Please see attached. One of the libraries in conflict is different from that described above, but the problem is the same. My development environment is 32bit v3.5.16.70 using v3.5.11.0 compiler.

Is it really the same CODESYS version with the same add-ons? Maybe open the CODESYS installer on your home laptop, and export the configuration. On your work PC open the CODESYS installer and import the configuration.

Hi, I have a Combivis studio 6 licence. What I need is information from Codesys about how the information 'Download time' is saved and if it is possible to modify it manually.

Hi, have the same problem. Tried various versions (3.5.17.0 3.5.18.5 3.5.19.0 3.5.20.1) When you compare two functions blocks inside one project, the compare function does work. Regards, Gerco

Post by timvh on library is not available ^{CODESYS Forge talk (Post)}
Which PLC do you use? If it is a standard CODESYS Runtime (from the store), then maybe update the device in your project to the latest version. If it is not a standard CODESYS Runtime, then maybe contact the supplier.

Post by testyhalftime on Version management ^{CODESYS Forge talk (Post)}
Hi Suyash! Stick to the IDE version used to create the project, and use Library Manager to fix version mismatches. Disable auto library updates and keep a record of working versions for stability. https://forge.codesys.com/forge/talk/Engineering/thread/0a4c242ab9/Italian Brainrot Clicker

Post by dkugler on Version management ^{CODESYS Forge talk (Post)}
If you update all to the newest versions in the project environment and update all devices in the device tree, the errors should gone! Missing the device updates is often causing this problems!

Hi, Is there a solution found for the problem described in first post? Any version above Codesys 3.5 P19 hangs during start up. It makes no difference whether I simply start Codesys or open a project directly. I'm using Windows 10 Home edition. Thanks!

Hello, Sorry for digging this topic up, but the bitbucket link does not work anymore. Have you changed the location @mondinmr ? I would be really interested in your project, even if you did not finish it. Thank you for your time, BR

Post by pouyavakili on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
❓ Issue: TestManager Not Available in Python Script (AttributeError) 🙏 Question: Why does project.get_testmanager() not work in scripting, even though Test Manager is installed and licensed, and the script runs in GUI mode? Is there a way to ensure the Test Manager interface is loaded or accessible from the scripting environment? 🧠 Summary: I'm trying to automate test execution using the CODESYS scripting engine (Python) via a script that opens a project, builds the application, and runs tests from a TestRepository.xml. Although the Test Manager works manually in the IDE, it fails when accessed via script with the following error: AttributeError: 'ScriptObject' object has no attribute 'testmanager' 🧪 Test Setup: CODESYS version: 3.5.21.10 Test Manager: Installed and licensed (works in the IDE manually) Project: Contains a test repository, which can be executed via the GUI Script execution method: powershell Start-Process -FilePath "C:\Program Files\CODESYS 3.5.21.10\CODESYS\Common\CODESYS.exe" ` -ArgumentList @( '--profile="CODESYS V3.5 SP21 Patch 1"', '--runscript="C:\Scripts\run_tests.py"' ) -Wait 📜 Script Summary: python project = projects.open(project_path) application = project.active_application application.build() This fails: testmanager = project.get_testmanager() ❗ Problem: Calling project.get_testmanager() or application.testmanager throws an AttributeError, even though the same project and test repository work in the GUI.

You should use PLCnext if your device-hw is a PLCnext-un it. As I understand it you are using "CODESYS Control Win V3 x64".
